Hi,

I'm new to the subject. I got a sam file and fasta file, I need to get all the allele ref = G alter = T with a specific depth. As I understand it I need to use samtools, but I never worked with it..can anyone get me in the right direction?

Hi sahar850

Since you are new to this subject (and thanks for letting us know that), you must first perform what is known as "variant calling". After that you will get a VCF file and then you can apply the depth based filters for .e.g see this post:

Filter SNPs on depth

Since you haven't mentioned any background information about your data, I am afraid if anyone would be interested in pointing you towards the right direction. Please see the below posts and reframe or re-write your question
